OBJECTIVE: In cleft palate patients, the soft palate is commonly closed using straight-line palatoplasty, Z-palatoplasty, or palatoplasty with buccal flaps. Currently, it is unknown which surgical technique is superior regarding speech outcomes. The aim of this review is to study the incidence of speech correcting surgery (SCS) per soft palatoplasty technique and to identify variables which are associated with this outcome.
METHODS: A systematic literature search was carried out according to the PRISMA guidelines. Inclusion and exclusion criteria were applied to focus on the incidence of SCS after soft palatoplasty. Additional variables like surgical modification, cleft morphology, syndrome, age at palatoplasty, fistula and assessment of velopharyngeal function were reported. A modified New-Ottawa Scale (NOS) was used for quality appraisal. Pooled estimates from the meta-analysis were calculated using a random-effects model.
RESULTS: One thousand twenty-nine studies were found of which 54 were included in the analysis. The pooled estimate proportion of SCS after straight-line palatoplasty was 19% (95% CI 15-24), after Z-palatoplasty 6% (95% CI 4-9), and after palatoplasty with buccal flaps 7% (95% CI 4-11).
CONCLUSIONS: A lower SCS rate was found in patients receiving Z-palatoplasty when compared to straight-line palatoplasty. We propose a minimum set of outcome parameters which ideally should be included in future studies regarding speech outcomes after cleft palate repair.
CONCLUSIONS: Current literature reports highly heterogenous data regarding cleft palate repair. Our recommended set of parameters may address this inconsistency and could make intercenter comparison possible and of better quality.

Intraoral injuries are frequently encountered in emergency departments due to children\'s desire and curiosity to put objects in their mouths. However, forward falls with objects in children\'s mouths can cause impalement injuries to soft palate, retropharyngeal-peritonsillar, and retromolar tissues, leading to serious morbidity and even mortality. These transoral (soft palate, pharynx-tonsil, retromolar region) penetration injuries can especially result in damage to major vascular structures like the Internal Carotid Artery (ICA) due to their close proximity. Dissection, thrombosis, and subsequent stroke can occur in the delicate ICA as a result. In the presented case, a 3-year-old male child experienced internal carotid artery dissection following penetrating injury with a pen, as demonstrated by imaging studies. A literature review is provided along with the case of this child, who developed a reduction in middle cerebral artery (MCA) flow due to thrombosis in the ICA. The study encompasses all penetrating oropharyngeal traumas reported in individuals aged 0-18 years from 1936 to 2023. A search in PubMed and Google Scholar using keywords such as \'internal carotid artery injury,\' \'penetrating trauma,\' and \'children\' yielded 78 case reports from a pool of 36,000 studies. The analysis excludes injuries in areas like tongue, cheek, gums, lips, and floor of the mouth, post-tonsillectomy injuries, and those from sudden braking vehicles. This review encompasses the evaluation, diagnosis, and treatment of penetrating injuries to the soft palate, pharyngeal wall, tonsil, and retromolar regions.

The aim of this systematic review was to determine whether one-stage palatoplasty for children born with cleft lip and palate shows overall advantages in outcome compared with two-stage palatoplasty. The included studies were controlled studies of syndromic and non-syndromic children born with unilateral cleft lip and palate, bilateral cleft lip and palate, or isolated cleft palate. The interventions studied were one-stage palatoplasty and two-stage palatoplasty starting with the soft palate. The outcomes were facial growth, speech, hearing, presence of fistulae, other complications related to surgery, health-related quality of life, and health economics. In total, 14 original studies were included. Results were dichotomized into showing advantage for one- or two-stage palatoplasty for the respective outcome and compared with the results from six included systematic reviews. No overall advantage for either surgical strategy was found for any of the outcome measures. The certainty of evidence was highest for the presence of fistulae, followed by facial growth and speech. For several outcomes, the quality of the existing evidence was too low to allow for any conclusions to be drawn. Neither one- nor two-stage palatoplasty showed significant advantages in clinical outcomes compared with the other. Other aspects such as ethics, economics, or surgeon\'s preference might hence be of more importance. Homogenous choices of outcome measures and defined minimal clinically important differences would facilitate further research.

Tissue adjunct is non-palatal tissue used to manage tension at the defect site by providing additional coverage. This review aimed to compare outcomes of various adjuncts employed in primary palatoplasty.
A literature search was conducted of MEDLINE, EMBASE, and Cochrane Library with keywords cleft palate, palatoplasty, surgical flaps, and allografts. Data extracted included demographics, cleft severity, primary/adjunctive techniques, outcomes, and follow-up periods. Logistic regression analyses and chi-squared tests were performed to investigate associations among variables.
A total of 1332 patients (aged 3 months-5 years) with follow-up of 1 month to 21 years were included. Cleft severity included submucous cleft (1.7%), Veau I/II (33.3%), Veau III (46.3%), and Veau IV (15.1%). Most reported techniques were Furlow (52%) and intravelar veloplasty (14.3%) for soft palate, Bardach (27.2%), and V-Y Pushback (11.1%) for hard palate. Buccal myomucosal flap (BMMF) was performed in 45.4% of cases, followed by buccal fat pad flap/graft (BFP) in 40.8% and acellular dermal matrix (ADM) in 14%. Severe clefts (Veau III/IV) were repaired more frequently with BMMF compared with ADM (p = 0.003) and BFP (p = 0.01). Oronasal fistula occurred in 3.1% of patients, and velopharyngeal insufficiency (VPI) in 4%, both associated with Veau IV (fistula: p = 0.002, VPI: p = 0.0002). No significant differences were found in fistula (p = 0.79) or VPI (p = 0.14) rates between adjuncts. In severe clefts (Veau III/IV), ADM was associated with fistula formation (p = 0.03).
Adjuncts in primary palatoplasty may mitigate unfavorable outcomes associated with severe clefts. BMMF is superior, given its inherent tissue properties, whereas BFP is effective in reducing fistula formation.

OBJECTIVE: The aim of this study is to analyze functional outcomes of soft palate reconstruction after oncologic surgery.
METHODS: This study was conducted in conformity with the PRISMA statement. A single arm meta-analysis was performed for feeding tube dependence (FTD) (primary outcome), velopharyngeal insufficiency (VPI) and hypernasality (HN) (secondary outcomes) incidences.
RESULTS: A total of 510 patients (males: 77.75%, n = 353/454) with a median age of 58 years (n = 480/510; 95% CI 57.0-61.0) who underwent soft palate surgical resection with primary reconstruction were included. Overall, the cumulative FTD rate was 1.55% (n = 28/510; 95% CI 0.24-3.96%), the VPI rate was 22.18% (n = 119/379; 95% CI 12.99-33.02%), and the HN rate was 33.01% (n = 88/234; 95% CI 19.03-46.61%).
CONCLUSIONS: Soft palate reconstruction results in a low incidence of FTD, and most patients resume a full oral diet. Both obturators, primary closure, local and free flaps seem good reconstructive options. Nevertheless, more specific postoperative functional deficiencies like VPI and HN owns higher incidences, potentially affecting the quality of the swallowing and speaking function and the patient\'s quality of life.

Leiomyosarcomas (LMSs) of the head and neck are an extremely rare entity. Of all smooth muscle tumors, 4%-10% occur in the head and neck and only 0.06% in the oral cavity. Because of its infrequency, it has been associated with both delayed diagnosis and misdiagnosis. Here, we report the clinicopathological findings of a case of primary LMS of the soft palate in a 42-year-old male patient with an emphasis on the judicious use of ancillary diagnostic modalities to arrive at a definitive diagnosis. Intraorally, LMSs present as painless, lobulated, fixed masses of the submucosal tissues in middle-aged or older individuals. The treatment modalities and lymph nodal dissection criteria are dissimilar to more common oral carcinomas. Hence, definitive diagnosis is necessary.

GLI1 fusions involving ACTB, MALAT1, PTCH1 and FOXO4 genes have been reported in a subset of malignant mesenchymal tumors with a characteristic nested epithelioid morphology and frequent S100 positivity. Typically, these multilobulated tumors consist of uniform epithelioid cells with bland nuclei and are organized into distinct nests and cords with conspicuously rich vasculature. We herein expand earlier findings by reporting a case of a 34-year-old female with an epithelioid mesenchymal tumor of the palate. The neoplastic cells stained positive for S100 protein and D2-40, whereas multiple other markers were negative. Genetic alterations were investigated by targeted RNA sequencing, and a PTCH1-GLI1 fusion was detected. Epithelioid mesenchymal tumors harboring a PTCH1-GLI1 fusion are vanishingly rare with only three cases reported so far. Due to the unique location in the mucosa of the soft palate adjacent to minor salivary glands, multilobulated growth, nested epithelioid morphology, focal clearing of the cytoplasm, and immunopositivity for S100 protein and D2-40, the differential diagnoses include primary salivary gland epithelial tumors, in particular myoepithelioma and myoepithelial carcinoma. Another differential diagnostic possibility is the ectomesenchymal chondromyxoid tumor. Useful diagnostic clues for tumors with a GLI1 rearrangement include a rich vascular network between the nests of neoplastic cells, tumor tissue bulging into vascular spaces, and absence of SOX10, GFAP and cytokeratin immunopositivity. Identifying areas with features of GLI1-rearranged tumors should trigger subsequent molecular confirmation. This is important for appropriate treatment measures as PTCH1-GLI1 positive mesenchymal epithelioid neoplasms have a propensity for locoregional lymph node and distant lung metastases.

BACKGROUND: The purpose of this study was to compare 2 techniques used for primary muscular repair and perform a systematic review of the literature to evaluate the effects of radical intravelar veloplasty (IVV) on nonsyndromic unilateral cleft lip and palate.
METHODS: This is an ambispective study between 2 groups of patients with unilateral cleft lip and palate who were operated using a radical and conservative form of IVV in Lima Peru. Data collection was accomplished by evaluation of speech development and middle ear function of the patients. A systematic review of the literature for studies published until June 2020 to evaluate the effect using the radical IVV in patients with cleft lip and palate.
RESULTS: Our comparative study did not find statistically significant differences in speech development between the studied techniques for unilateral cleft palate repair. Increased number of ear tube placements have been observed in the group treated with radical form of IVV. After systematic literature searching, 10 identified studies were qualified for the final analysis, which included 1367 patients. The overall study quality according to Oxford CEBM and GRADE scale was low.
CONCLUSIONS: The results arising from this study provides statistical evidence that one technique let us obtain better speech outcomes. A technique with conservative IVV has statistical significant fewer rate of middle ear disorders after primary cleft palate repair. Based on available scientific evidence, definitive conclusions about the effectiveness of radical IVV on velopharyngeal and middle ear function cannot be drawn.

To investigate prenatal diagnosis characteristics and pregnancy outcomes associated with isolated right aortic arch (RAA).
A retrospective study including fetuses with isolated RAA, managed between January 2010 and February 2018. Cases were identified from the ultrasound databases of the expert pediatric cardiologists, who made the aforementioned diagnosis. All fetuses were examined by a fetal medicine imaging expert to exclude any extracardiac abnormality. A systematic review was performed to assess the prenatal diagnosis and outcomes of fetuses with isolated RAA.
Fifty-six fetuses were diagnosed with an isolated RAA. An isolated double aortic arch (DAA) was diagnosed in one fetus. Mean gestational age at diagnosis was 24 weeks. The sex ratio (boy/girl) was 0.89. No significant abnormality was detected in invasive tests (karyotype and FISH or microarray). Only one fetus was misdiagnosed with isolated RAA. He was the only symptomatic (stridor) newborn baby and was later diagnosed with DAA. Four studies were included in our systematic review representing 115 cases of isolated RAA. One significant chromosomal abnormality was detected: a 22q11 deletion in a newborn baby who had a postnatal finding of a soft palate cleft. There was one major obstetric complication: an intrauterine fetal demise at 41 gestational weeks.
Diagnosis of isolated RAA can be challenging. Invasive tests are to be discussed. The diagnosis of isolated RAA should not change obstetric monitoring. Nevertheless, an echocardiography should be performed systematically in these new newborn babies within their first month of life.

To evaluate the long-term efficacy and potential predictors of uvulopalatopharyngoplasty (UPPP) among adult patients with obstructive sleep apnea (OSA).
A systematic search was conducted through PubMed/Medline, Embase, Web of Science, and the Cochrane Library until December 2018.
Full-text articles were selected that studied adult patients who underwent single-level UPPP or its modification for OSA and had a long-term follow-up (at least 34 months) with objective sleep study results. Studies that had no objective outcomes or performed other surgical procedures for OSA were excluded.
Of 2600 studies, 11 were included. Meta-analysis comparing long-term post- and preoperative outcomes showed significant improvements, with an 15.4 event/h (46.1%) decrease of apnea-hypopnea index. Compared with the short-term outcomes (3-12 months), the long-term outcomes were less effective, with apnea-hypopnea index increasing 12.3 events/h (63.8%) and the surgical response decreasing from 67.3% to 44.35%. Subanalysis of individual patient data showed significant correlations of baseline body mass index, lowest arterial oxygen saturation, and proportion of sleep time with oxygen saturation <90% with long-term surgical response.
Despite the surgical efficacy decreasing over time, UPPP and its modification are an effective surgical method for adult OSA in both the short term and the long term after the surgery. Baseline body mass index, lowest arterial oxygen saturation, and proportion of sleep time with oxygen saturation <90% were potentially predictive for long-term surgical response. Case-control studies of the long-term surgical effect of OSA are needed.
